Mold in Bakeries:
How Can You Prevent Contamination in Baking Facilities?
Hygiene in bakeries is an ongoing challenge for professionals. In fact, the conditions under which products are baked and packaged promote mold growth in bakeries. Photoclean harnesses the properties of UV rays to offer you an air decontamination solution for the food industry that is unique in France.
Why do bakeries get mold?
Most baked goods have a high moisture content, which creates an ideal environment for the growth of food-borne molds. The temperature and humidity conditions in production facilities—resulting from the baking of bread and pastries—increase the risk of contamination.
The Aw value indicates the availability of water in a product for the growth of microorganisms. The higher this number, the greater the risk of contamination. Measuring the Aw value allows for adjustments to environmental conditions or the drying process in a bakery production facility.
Certain factors accelerate the growth of spores and mold: underbaking, bread packaged while still hot and moist… When combined with contaminated indoor air and inadequate hygiene procedures, the risk to food safety is very real.
Which baked goods are particularly prone to mold growth?
In the food industry, the BVP sector—bakery, pastries, and confectionery—is among the most vulnerable to mold contamination. Among the products most affected are:
- Sliced bread: Its soft texture and high moisture content facilitate the establishment and growth of spores.
- Crustless bread: Without this natural protection, it is even more susceptible to microbial and fungal contamination.
- Long-shelf-life foods: even when packaged in a modified atmosphere, even the slightest recontamination can lead to significant losses.
Consumption of sandwich bread is on the rise, particularly that of crustless varieties, which have become a flagship product in the industry. This commercial success heightens the challenges of mold control in bread production: the higher the demand, the more essential quality management becomes.
How Can Food Safety Be Ensured in a Bakery?
Limiting the risk of fungal contamination in the bakery industry requires a comprehensive strategy. Manufacturers must take action at every stage of production and packaging to:
- adapt processes and the storage environment to the products’ moisture content;
- prevent condensation to avoid mold growth inside packaging;
- adjust product baking and cooling parameters to reduce spore survival rates;
- adopt strict hygiene practices: prevent cross-contamination by cleaning production lines and controlling airflow.
What does the PhotoClean air treatment solution for the food industry consist of?
As an expert in industrial air treatment, Photoclean meets the needs of professionals across all sectors. Our products are particularly well-suited for use in bakeries.
The principle behind our treatment modules is as follows: air is directed past a UV-C lamp, whose effectiveness is greatly enhanced by a medium we have developed. This medium extends the exposure time of microorganisms to the rays and increases the contact surface area for optimal results. UV light blocks the growth and reproduction of mold, bacteria, and viruses, leading to their permanent destruction.
The Photoclean system offers three advantages:
- Temperature and humidity control are separate from contamination treatment.
- Temperature and filtration requirements are reduced.
- Our solutions are more energy-efficient and take up less space.
With our solution, there’s no longer a need to use very low temperatures to limit contamination from spores and mold, which in turn reduces your operating costs. Ensuring food safety and extending product shelf life becomes simpler and less expensive.
